Figure 5-1.
AC waveforms for read operation (1)
Notes:
1. Timing measurement references are 0.8V and 2.0V. Input AC drive levels are 0.45V and 2.4V, unless otherwise specified.
2. t DF is specified form OE /V PP or CE , whichever occurs first. Output float is defined as the point when data is no longer
driven.
3. OE /V PP may be delayed up to t CE - t OE after the falling edge of CE without impact on t CE .
4. OE /V PP may be delayed up to t ACC - t OE after the address is valid without impact on t ACC .
5. This parameter is only sampled and is not 100% tested.
